Update maxed screen resolution
by echidnagirl from LinuxQuestions.org on (#4Y64K)
The reboot from the latest update (in Mint 19.3 Update manager suggestions as per 19 Jan 2020) maxed out my screen resolution and I can't find a way to fix it using the gui or terminal. I have tried the following:
1. Using the gui Timeshift to revert one step - can't see the 'GO' button
2. Ran xrandr --listactiveterminals -> failed to get size of gamma for output default
3. Ran xrandr -s 1440x90 -> not my screens res but worth a try ->not found in available modes
4. Ran rm ~/ .config/monitors.xml -> with and without spacing btw / and . same result -> no such file or directory
5. cd/ -> to go to root - bash: cd/: no such file or directory
6. Checked the Mate Terminal Manual for 'root' '.config' 'resolution' - nothing
7. Searched LQ Newbie forum for similar prob. Nothing that matched or was close.
8. Tried to log in as root -> permission denied! It's my computer!
Aaarrgghhh. Please help.
Possible coincidence that my graphics card failed at THAT PRECISE time?
Thank you in advance for your help,
